Why does loopback mode trump GPPE drive maps but not GPO user logon script?

I recently migrated my users to a new GPO structure, taking advantage of numerous Group Policy Preferences. I’ve stumbled on to an issue where users’ drive mappings are not being made when they log into a conference room computer.

These conference room computers have loopback enabled (“Replace”) so I can lock several, albeit minor, settings down. The drive mappings are done via User GPPE > Windows Settings > Drive Maps. In the old days, I did it with a GPO user logon script (which worked). The GPPE drive maps do not work.

If I change the loopback mode to “merge”, it will work, but then I lose my ability to lock stuff down.

Anyone have an explanation or advice how to get around this?

To start with: you don't lose the ability to "lock stuff down" with Loopback processing in Merge mode.
All that Loopback mode does is tell the OS to apply user configuration GPOs based on the OU where the computer account is.
In "Merge" mode, the user configuration GPOs will be applied based on the user object's location in AD first, then the user configuration GPOs based on the computer object's location in AD (so that with concurrent policies, the one applied via Loopback will always win).
In "Replace" mode, any user configuration GPO based on the user object's location in AD will be skipped altogether, and only the ones linked to the computer object's location will be applied.
So you can either use "Merge" mode, making use of the Loopback's higher priority to lock down whatever was allowed in the default GPOs, or you can use "Replace" mode to log the users on with a clean slate, put all the drive mapping GPPs into their own dedicated GPO, and link the drive mapping GPO not only to the user OU, but to the conference room OU as well (or duplicate the GPPs, but if you need the same drive mappings, then that's not really the best solution).
